a πρεσβύτερος, a more senior dignitary, one who effects because of his distinguishment.

(which is eventually brought about by Her abiding in us[a][b] for
the truth’s sake, which remains in us,-- as She always[c]
will be). and it will be with us forever:

a The Truth abiding in us is developing us: eventually, we come to recognize God's still, small voice, then grow in ability to heed Him over all; this requires devoting attention to studying (hearing and reading analytically) while building working conceptual models -- fitly, from analytical bits -- to put to practice in our lives.

b Seeing the Son and being saved is the first step into Life;
recognizing and following The Truth is an ongoing Life Journey (cf. 3John 7).

c είς τὸν αἰῶνα, unto all time itself, which is a created thing we exist in, like fish in water.

¶I was very gratified[a]rejoice greatly that I

the Father.

a RP: παραβαίνω, to walk away. NA/UBS: προάγω, to precede (here, to move on? BDAG s.v. προάγω 2, 2J 9: anyone who goes too far...). Whether leaving (backsliding) or getting ahead of Christ's teaching (prematurity, especially in so-called church leaders building THEIR 'ministries'), the results are similar: dead works of the flesh, not by the Spirit; the Father's development of the Son in an individual is an incremental, line upon line, precept upon precept process that takes time -- it's gradual.

b continuing in Christ's teaching involves treasuring it up, not letting it go in one ear and out the other.

c lit. continuing in Christ's teaching -- actively, not merely tolerating, awaiting, or relying on others (e.g. church leaders); this brings true spiritual development, growth by the Spirit through the Word's watering.

a οὐ φέρει.

b i.e. of Christ coming into people.

c εἰς οἰκίαν, into inner activity, i.e. the things being carried on; not εἰς τόν οἰκίαν, into the house.

d i.e. maintain distance (you're separated for God's purposes from the world and not to accomodate worldly stuff).
